Three-phase
CA368-C57
Three-Phase Split-Type Prepayment Energy Meter
The CA368-C57 is a three-phase multi-function meter with embedded communication modules.The meter is used to accurately measure electrical energy for commercial,industrial, and residential customer and is suitable for environments with unstable voltage.This meter can be used for post payment applications(optional by company),The CA368-C57 has outstanding anti-tamper feature like terminal cover open detection sensor to help utility for revenue protection. The CA368-C57 can utilizes PLC, RF or Cable communication to ClU as an option.
Introduction
Introduction
Split Configuration for Increased Revenue Protection
The meter consists of two parts, the MCU (Metering & Control Unit) and CIU (Customer Interface Unit). The MCU and CIU is linked via galvanically-isolated 2-wire communication cable or RF communication is also available on request.
The CIU is installed within consumer’s home for prepaid token input and info inquiry, while MCU is installed in a meter cabinet away from consumers.
